If you get the information about your hubs, you should be able to do a rebuild of the hub and replace the back seal without needing to change to grease.
The ranger hub as you know is an oil bath hub, so the rear seal actually is a double lipped seal. When you replace it, the metal portion of the seal (butts up to the hub) should be coated with some sort of RTV silicone that is impervious to oil or solvents before you tap it into the hub.
Be sure to thoroughly clean the surfaces of the hub where the bearing seal rests, the spindle, and the surfaces for the front cap as well.
When you reinstall the hub, tighten down as you normally would with greased bearings to set the bearings, then loosen/retighten the castle nut to eliminate any freeplay. rtv silicone on the cap before install, then fill up the hub with oil. From there, you should be good to go.
